Winterwarm XR Heater The Winterwarm XR: efficiency, energy saving and total comfort control through unique design characteristics. An indirect fired unit air heater with an innovative burner and heat exchanger combination, and of course provided with the latest control technology. The compact measurements and the high level of comfort make the XR suitable for many applications in all environments such as showrooms, retail stores, sports centres and even in restaurants, but also in the traditional industrial environments. One of the unique characteristics of the XR is that the heater can be suspended in any desirable position; horizontal, vertical or at any angle in between. Therefore easily directing the airflow in the direction required. When blowing out vertically, the heater also functions as a Destratification fan. Installation in difficult corners is no longer a problem: one simply turns the heater upside down. The burner and the fan are both modulating (down to approx. 60%): the room is brought up to temperature at full load and consequently kept at the desired temperature on partial load. The energy consumption and the noise level are reduced to a minimum while the comfort level increases as there are fewer fluctuations in the room temperature. The XR series uses an advanced control system which increases the comfort even further. Two temperature sensors, one within the heater and one in the room, measure continuously the temperature gradient. Should the temperature gradient increase beyond the set value, the unit will switch on the fan and circulate the warm air. The gradient control in combination with the modulating burner and fan can realize energy savings up to 15% in comparison with conventional unit air heaters. Of course the XR is also provided with a summer ventilation possibility for continuous air circulation. Both XR-models have 2 suspension possibilities. The first Bracket for horizontal or vertical air distribution consists of 3 U sections, 2 of which are mounted to the heater and 1 to the wall or to the ceiling. Also available are extension pieces of 1 m. and clamps for mounting the bracket to a steel H section. The design bracket can rotate in both the horizontal and vertical direction; consequently, the heater can blow in any desired direction. This bracket is suitable for mounting on a wall or ceiling. The XR also has 4 recessed suspension points in the corner for M10 threaded bar. This allows the heaters to be suspended in the conventional manner. The XR-series is controlled by the DB 8, a 7-day programmable thermostat, which gets the best from the heater. Thanks to a number of functions which are simple to operate, a maximum comfort level can be achieved at minimum energy consumption. The DB 8 incorporates an optimizing program, therefore determining the start time of the heaters enabling the building to be at the correct temperature at the desired occupancy time. The DB 8 is provided with the following functions: 7 day programme 10 different on / off programs Permanent display of the room temperature Modulates on room temperature Frost protection Keyboard locking Manual override Summer ventilation Compensation for the influence of walls Controls 1-8 heaters Failure diagnosis and reset per unit air heater Wired in twisted pair screened cable Also available is the optional interface board for building management systems (0-10 V) Magma Energy Services Ltd offers a complete design and installation for Winterwarm heaters with warranty options from two to five years. A full range of industrial heating services is available. Philip Hamer |
